Today, 3286 days later, it counts 14 200 commits only in development branch.

Some statistics about project evolution and development were made available on web site – click here to see them!

There are interesting facts about most productive time frames (i.e., hour, day, …), evolution of default configuration files, command line parameters, … IPv6 support is there since 2002, but no convenient public network to use it yet.

Enjoy and enhance the content as you have interesting aspects of history to add…

… and, VERY important, do not forget to start testing 3.1.0, we are in pre-release phase, there are a lot of new features you surely want on your production system:

http://sip-router.org/wiki/features/new-in-devel

Keep your eyes on following pages to learn how to upgrade from 3.0.x and know what is new in v3.1:

• http://sip-router.org/wiki/install/3.0.x-to-3.1.x
• http://sip-router.org/wiki/features/new-in-devel

They are going to be updated to reflect properly next version.

Testing and feedback is very much appreciated, email us at sr-dev [at] lists.sip-router.org.

Note that the days before, Amoocon 2010 takes place in Rostock, Germany, and SIP Router project is present with two presentations about Asynchronous SIP Processing and Doing SIP Routing in Lua.

The days after the devel meeting, LinuxTag 2010 takes place in Berlin, where our project has a presentation about Distributed VoIP platforms and a stand for the entire duration of this event – 4 days – come and visit us at LinuxTag!

For USA, there is a plan to schedule a social networking event on June 22, tied to Advanced Training for Carriers – if you are interested to join the event in Miami, please send an email to registration@lists.sip-router.org.

• CeBIT 2010, Hannover, Germany, March 2-6 – you can meet Daniel-Constantin Mierla, Elena-Ramona Modroiu, Marcus Hunger and Carsten Bock from Kamailio Management Board
• Social Networking Dinner, London, UK, March 9, tied to Present and Future of SIP Routing (London, UK, March 9) and UC Expo (London, UK, March 10-11)
• Social Networking Dinner, Berlin, Germany, March 25, tied to Kamailio SIP Router Masterclass

Stay tuned for more updates about SIP Router project!

• seven new modules
• additions to pv, blst, uac, xlog and tm modules
• new parameters in core

Among new things: config file step-by-step debugger, Lua and Python API for config file, message queues and in-memory tree data containers. See more at:

http://sip-router.org/wiki/features/new-in-devel

Siremis enables straightforward management of subscriber profiles, least cost routing and load balancing rules, communication at runtime with the SIP server, displays monitoring charts. Read more at:

http://sip-router.org/tarballs/sr/

Note that new tarballs are generated only if there are changes for the corresponding branch (so if you don’t see a tarball with today’s date it means there was no change from the previous one).

The tarballs are generated via make tar, which makes sure the correct repository version will be included in the compiled binary (make tar generates first autover.h before creating the archive).

More details to follow soon! Stay tuned!

pdb server

This server loads serialized routing data from the disk and stores it in memory. It then listens on an UDP port for requests containing a number and returns ID of the carrier which owns the number. This server uses the same datastructure as the carrierroute module and provides a really good performance — consumes only a few percent CPU, even you use only one server for your complete call routing cluster.

pdb connector module

This module connects the sip-router server to the pdb server. It supports load-balancing and aggressive timeouts. Normally it does not need more than a few ms to query the remote server and return the reply to the configuration script.

pdb tool (data compiler)

This tool provides the functionality to compile the carrier and number informations into the binary data format the pdb server expect. It supports optimizing the generated trie structure, so that for example the complete number to carrier mapping for Germany (app. 150 million numbers) don’t need more than a few hundred megabytes. You can also combine not interesting carriers in order to save even more space and get better performance.

The module can be in the modules/pdb directory, the server and tool is in utils/pdbt. This directory also contains documentation (README for module, utils/pdbt/docs/* for data format and network protocol).
